How to Upgrade an Application System to CA Gen

Create a strategy for supporting production systems that are generated before COOL:Gen 6.0, during and after conversion to CA Gen Release 8.5.

Follow these steps:

1. Understand the differences between code that is generated with CA Gen Release 8.5 and code that is generated with earlier versions.

   Consider the effect of the new features and functions in all releases since the current release.

2. Review construction procedures.

   Consider the effect of the changes to generation and installation on Release Management procedures.

3. Create a system inventory.

   Identify the systems to regenerate. For each model, record the following information:

   • Ownership
   • Size, such as the number of objects
4. Determine an application support option.

   See the section on Application Support options in the Considerations for Application Support section and determine the best option for upgrading the system.

5. Sequence the application systems to regenerate.

   Determine the sequence for upgrading the application systems. When determining the sequence, make the following considerations:

   • Are there dependencies between the systems?
   • Are there any ongoing development projects on these systems?
   • Is the system critical to the business?

After you determine the systems to regenerate, develop a plan for each system.
